By Burton:
"Castro succeeds, who Lusias estandard
shall bear for ever in the front to wave;
Successor the Succeeded's work who endeth;
that buildeth Diu, this builded Diu defendeth."
1648.—"At the extremity of this Kingdom, and on a projecting point towards the south lies the city Diu, where the Portuguese have 3 strong castles; this city is called by both Portuguese and Indians Dive (the last letter, e, being pronounced somewhat softly), a name which signifies 'Island.'"—Van Twist, 13.
1727.—"Diu is the next Port.... It is one of the best built Cities, and best fortified by Nature and Art, that I ever saw in India, and its stately Buildings of free Stone and Marble, are sufficient Witnesses of its ancient Grandeur and Opulency; but at present not above one-fourth of the City is inhabited."—A. Hamilton, i. 137; [ed. 1744, i. 136].
DIUL-SIND, n.p. A name by which Sind is often called in early European narratives, taken up by the authors, no doubt, like so many other prevalent names, from the Arab traders who had preceded them. Dewal or Daibul was a once celebrated city and seaport of Sind, mentioned by all the old Arabian geographers, and believed to have stood at or near the site of modern Karāchī. It had the name from a famous temple (devālya), probably a Buddhist shrine, which existed there, and which was destroyed by the Mahommedans in 711. The name of Dewal long survived the city itself, and the specific addition of Sind or Sindī being added, probably to distinguish it from some other place of resembling name, the name of Dewal-Sind or Sindi came to be attached to the delta of the Indus.
c. 700.—The earliest mention of Dewal that we are aware of is in a notice of Chinese Voyages to the Persian Gulf under the T'ang dynasty (7th and 8th centuries) quoted by Deguignes. In this the ships, after leaving Tiyu (Diu) sailed 10 days further to another Tiyu near the great river Milan or Sinteu. This was, no doubt, Dewal near the great Mihrān or Sindhu, i.e. Indus.—Mém. de l'Acad. des Insc. xxxii. 367.
c. 880.—"There was at Debal a lofty temple (budd) surmounted by a long pole, and on the pole was fixed a red flag, which when the breeze blew was unfurled over the city.... Muhammad informed Hajjáj of what he had done, and solicited advice.... One day a reply was received to this effect:—'Fix the manjaník ... call the manjaník-master, and tell him to aim at the flagstaff of which you have given a description.' So he brought down the flagstaff, and it was broken; at which the infidels were sore afflicted."—Bilāḍuri, in Elliot, i. 120.
